PIP review outcome (dates)

Please can I ask, I have received the decision about my PIP review award, and the outcome is the same as the previous award with no change. It says I will continue to receive the same award ‘from this date (2nd June 2026) for an ongoing period’.
Please can I ask if you have any idea what ‘an ongoing period’ means please?
As this is worded differently to my original first award letter, which stated specific dates the award started and ended of just over 4 years.

Thanks for your reply. Yes I can now see (on pg 2 of the PIP review letter) that it’s says I will be contacted again to see if needs have changed after 01 June 2036. I won’t be at state pension age by then.
